Help needed - tote/shoulder bag !!

[kittybelly]

Hi people, I need help! I want a pratical, light-weighted and big bag. And the straps of the bag shouldn't be thin(hurts the shoulders if its heavy right?)

I am a student therefore files, papers, water bottle and basic stuffs will be included in the bag. I need a good bag for school,

please show me pictures and tell me why you think it's good. Responses are kindly appreciated!

Go to Bluefly and look at the Prada nylon totes. I don't own any, but everyone that does say you can come short of dropping a nuke into them and they hold up well. Certainly, they are lightweight.
